I host a site which carries a lot of instruction manuals. Each page of the instruction manual is displayed with a table of contents for the manual, to aid easy navigation. The table of contents for all the manuals are all pretty similar but the content is mostly different. Running a test on copyscape, I was surprised to find that most of the pages that have "low content" i.e mainly images are coming up as duplicates because of the TOC displayed. Is there anyway I can tell google, that the TOC is a menu or similar, so that they don't think the pages are all duplicates?
